tubes a and 6.

Be it known that I, ACG'USTE DESI-ZACK, a

citizen of the Republic of France, residing at Producing Highly-0zonized Air or Oxygen,

(for which i have obtained Letters Patent in France under date of September 8, 1903, No. 335,092,) of which the following is a specification.

The present invention consists of an apparatus used in producing electric effluvia for generating highly-ozonized air or oxygen on a large scale.

This apparatus comprises a series of ozonizing elements or tubes so grouped as to form a considerable efliuviating-surface within a small space and so combined as to operate economically at a low temperature.

Figure 1 is a cross-section on the line 1 1 of Fig. 2, showing one form of ozonizing element. Fig. 2 is a longitudinal View of the same, parts being broken away. Fig. 3 is a cross-section on the line 3 3 of Fig. 4, showing another form of ozonizing element. Fig. 4 is a longitudinal view of the same, parts being broken away. Fig. 5 is a longitudinal section of the inner tube of an ozonizing element with its piping. Fig. 6 is a perspective view of the herein-described apparatus with one side removed. Fig. 7 is a diagram, showing a mechanical arrangement to be hereinafter described. Fig. 8 is a diagrammatic side view, partly broken away, of the entire apparatus; and Fig. 9 is a side view, partly in section, of one end of an ozonizing unit or element, showing the three tubes of different lengths.

Each ozonizing element is formed of three tubes, two of which are made of some elec trioally-conducting material and the third of some non-conducting material fitted with slight friction Within each other.

In the form illustrated in Figs. 1 and 2 the two conducting-tubes o and 6, preferably made of metal, are polygonal. The non-conducting tube c, preferably made of glass, is cylindrical and is placed between the two The threctubes are introduced into each other, as shown in end view in Fig. 1, the glass tube being made to protr'ude at each end fora sufficient distance to avoid direct discharges, as shown in Fig. 9. The outer conducting-tube b is connected to one pole of an electric generator, (not shown) and the inner conducting-tube a is connected to the other pole. Under the action of the electric current eflluvia are produced in the hollow spaces 7, Fig. 1, formed between the various tubes. The sides of both tubes'a and b are placed parallel to each other. The number of sides should be all the more great, as the sides are closer together. i

In the form shown in Figs. 3 and 4 the conductin tubes a and b are cylindrical, the metal being longitudinally depressed at a and b at three equidistant points, outwardly as regards the on ter tube 12 and inwardly as regards the innertube a. drical depressions a Z act to receive nonconducting rods 6, preferably glass, which on the one hand project internally and on the other serve to insulate he cylindrical tube 0 and to keep it equidistant from the tubes a and 6. Obviously the two metallic tubes 0. and b are of a different diameter in order to provide for the reception of the glass tube 0 and also to provide annular spaces d, wherein efliuvia may be formed} v The cooling of the inner ozonizing metallic tube a, of either form shown in Figs. 1 and 2 or 3 and 4 is effected as follows: The said tube (shown separately in longitudinalsection in Fig. 5) is closed at one end at f. The other end is closed by a wall or plug f, through which pass two small pipes g and h, the one, h, ending near the end f and the other, g, beginning at the opposite end f. The cooling liquid introduced through the pipe g, for instance, flows into the tube a, and after about filling the same it leaves through the pipe h.

I will now proceed to describe the manner in which the herein-described ozonizing elements are grouped together to form an apparatus having a large surface capable of operating economically at slow temperature, and consequently in the most favorable conditions for obtaining a maximum production.

Referring to Figs. 6 and 8, 'i represents a closed chamber, wherein are assembled a series of ozonizing elements or tubes, either of the form shown in Figs. 1 and 2 or of that shown in Figs. 3 and 4. One end of the tubes (1 b passes through one side wall of the charm her i, into which it is fastened, and opens into an air-chamber while the other end passes through the opposite wall of the chamber t,

The semicylin-- in the into which it is likewise fastened, and opens into an ozone-chamber 7c. At the top of ,the chamber i are a series of small metal tubes i, which are or may be fastened in the same manner as the ozonizing-tubes a b andare placed above the latter, one end of said tubes 7, opening into an inlet-chamber Z and the other into a chamber m. Above the tubes t" is a perforated plate n, acting as a bottom for a chamber n, which receives the cooling liq- .uid supplied from the vat 0 by a pump 1 connected' to a I feed-pipe 0'. Inside the airchamber 7', which is in free communication with the chamber m, is placed what may be termed a distributer, the purpose of which is to supply the cooling liquid to the whole of the central ozonizing tubes a. It comprises a feed main g, from which branch oil" a series of feed-tubes 9, closed at their outer end and provided with a series of feedpipes 1 each ofwhich is connected by a coupling g Fig. 5, or otherwise with the inlet-pipe g. Italso comprises an outlet-main p, from which likewise branch off a series of outlet-tubes p, also closed at .their outer end and provided with a series of outletpipes h, each of which is connected by a coupling h Fig. 5, or otherwise With the outlet pipe h of tube a. The mains p and q are supported upon non-conducting bases p -and (1, insulating them from the bottom 9', which supports them, The said mains should be sufiiciently distant from the inner walls of the chamber 7' to prevent direct discharges. They are insulated from the wall 7 by suitable non-conducting collars, (not shown,) through which they pass, the said mains acting, as will be readily understood, to also conduct the electric current to all the inner ozonizing-tubes a, Figs. 1, 3, and 6.

The cooling liquid raised from the vat 0 divides into two streams, one of which is led by the pipe 0 to the chamber n and falls onto the perforated bottom n, while the otheris led to the feed-main g. Now as the cooling liquid is connected to one pole of the enerator and as the distributor is connecte to the other it necessarily follows that the current will be transmitted from one pole to the other through the liquid supplied to thesaid istributer. This inconvenience is prevented by the mechanical contrivance shown diagrammatically in Fig. 7, by means .of which Y the liquid may be conveyed without current being transmitted. The contrivance comprises two superposed buckets s s, insulated from each other, the axes t t of which are mounted in suitably-insulated brackets. (Not shown.) The cranks u it, fast uponthe axes t t, partake, together with the rods 0 v, rocking movement of the buckets. When empty, the buckets, which. are heavier at the rear, rest upon two supports an ac and as sume the position shown. The rods o are suitably insulated and may slide with their free .per buckets is prevented from ends upon stationary stops 1 y. The action is as follows: The liquid supplied from the vat 0 falls into the upper bucket s, and when it has risen therein to a given level equilibrium is destroyed and the bucket is tilted, it's contents discharging into the bucket s. At the same time the rod o moves downward and lies with its free end in front of the projection 2, thus preventin the lower bucket s from rocking forward under the weight of the charge therein contained. When empty, the. upper bucket s resumes its ori 'nal position and the rod 12 as it rises aban ons the projection z and frees the lower bucket s, which is then at liberty to rock. In so doing the uprocking and emptying its contents, owing to a mechanism similar tothe one described. A like mechanical contrivance is provided for the return of the liquid to the veto.

The air to be ozonized requires to be dried and deprived of impurities therein contained in suspension. To that end it is conveyed to apparatus wherein it is caused to travel through concentrated sulfuric acid, after which it is introduced into vessels containing caustic potash, wherein it is deprived of particles of acid which may have been entrained. The air is then led into the inletchamber Z, Fig. 6, whence it passes through the series of cooled tubes 71, taking the tem-' perature of the latter, and is then led to the chamber m, after which it passes to the airchamber 3' and then through the spaces 1, Figs. 1 and 3, of the ozonizing elements into the ozone-chamber In, it being thenhighly ozonized ready for use. During this time the liquid, suitably cooled in the vat 0 by an ice-machine or otherwise, is raised by the pump (not shown) and is partly conveyed into the chamber n by the supply-pipe 0, falling through the perforated plate 'n, onto the air-tubes t" and onto the outer tubes 1) of the ozonizing elements and returnin to the vat o. The other part of the liqui is conveyed by the insulating contrivance shown in Fig. 7 into the feed main g, Fi 6, and is returned by the outlet-main p and a like contrivance into the vat 0.

One pole of the electric generator producing a current of suflicient tension is connected to the vat 0, and the other is connected to the distributer'g.

In Fig. 8 the entire apparatus is shown diagrammatically. 0 represents the tank in which the elements are located. From this tank the liquid is drawn by a ump 1 and forced through the pipe 0 into t e top of the tank, where it is showered down tubes and the ozonizing units or elements.

The pi e o is provided with a branbh 2,

which elivers liquid into the distributer g by means of tilting vessels. (Shown in detail in Fig. 7. (The liquid passes through the ozonizing elements, out through the outlet-main p,

over the airthrough a current-interrupter, such as shown in Fig. 7, and back into the tank. The air or oxygen to be ozonized is circulated through the tank by any suitable means. (Not shown.) 3 represents an electric generator of any desired type, one connection 5 being led to the tank 0 and the other 4 to the distributer g. The distributer g and outletmain p are of courseinsulated from the tank 0 .in order to prevent short-eircuiting.

It obvious that either form of tubes shown in Figs. 1 and 2 or 3 and 4 may be used. The insulating-tubes may be made of glass,porcelain, 'n'ncanite, or other like substance The conductmg-tubcs may likewise be ol any suitable metal, such. as aluminium, copper, nickel, alloy, or plated metal.

The apparatus may be arranged for using cooled compressed air under pressure and expanded, thus enabling the temperature to be reduced nutterially.

The operation may be carried on in three manncrs by iorcing air or by suction or by forcing and suction combined.

in the event of the internal or eivternal pressure exceeding an injurious limit two sat ety-valves may be supplied to the airchamber j, one opening inwardly and the other opening outwardly, both valves being so regulated as to allow air to enter or escape the moment the external or internal pressure tends to become excessive.

The apparatus may be utilized for treating air, oxygen, and generally all gases capable of being ozonized.

it is evident that in the hereiii-described ozonizer it will be possible to employ compressed air which will have been under pressure and will be made to expand in the airclunnber.
